Abstract (en)

[origin: EP0769521A1] Curing systems for fluoroelastomers curable by peroxidic route which comprise bromine, optionally iodine, the bromine always being higher than iodine, comprising as essential elements: (I) a curing agent comprising a bis-olefin having general formula: <CHEM> wherein: R1, R2, R3, R4, R5, R6, equal to or different from each other, are H or alkyl C1-C5; Z is a linear or branched alkylenic or cycloalkylenic radical C1-C18, optionally containing oxygen atoms, or a (per)fluoropolyoxyalkylenic radical. (II) a metallorganic hydride of formula: <CHEM> wherein: M is selected from Sn, Si, Ge, Pb; x is an integer from 1 to 3; y, z are zero or integers from 1 to 3, with the proviso y + z = 4 - x; w is an integer from 1 to 3; the R groups, equal to or different from each other, are selected from: alkyls C1-C4, aryls C6-C12, arylalkyls and alkylaryls C7-C14, optionally containing nitrile and/or hydroxyl groups.
